No jam & external leakage under frequently on/off operating;
Zero leakage — both internal & external leakage;
Flexible seat design reduces operating torque;
Quantitative compression design ensures all parts' stress below allowable limits to control cold flow of soft material.
Seat is high-performance polymer material with felxible seat design and ball is hardened.
High-frequency ball valves is one of most critical valves, only very few manufacturers (<5) has the capability to design and produce this valve.
ATW is one of five manufacturers and developed high frequency soft and metal seated ball valves since 2015. Till now ATW's high frequecy PDS ball valves have been widely used in many clients's site.
